COWL VENTILATOR.

`Application filed October *29, 1923. Serial No. 671,608.l

This invention relates Ito Aventilators and refers more particularlyvto cowlventilators for vehicle bodies.

'An object of the invention isfto provide a strong and durable ventilator that is'simple inlconstruction'and'that'may be easily and quickly adjusted for controlling the passage of air t-hrough the cowl of a-vehicle body.

Anotherobject is to provide simple land efficient means for automatically retaining the ventilator cover in any adjusted position. With the above and other objects in'view the invention consistsin certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a toppplan view of aportion of a vehicle andshowinga cowl ventilator embodying my invention applied'thereto;

Figure 2 is a sectional view taken'on line 2 2 of Figure;

Figure 3 is an enlarged central longitudinal vertical sectional view through `the cowl with parts in elevation. l

Referring now to the drawings in which like characters of reference designate correspondingparts throughoutthe several views, the numeral 1 designates a cowl of aveliicle body'having an air` inlet opening 2 :and an upstanding transversely Scurv-ed flange 3. This flange preferably extends'around the edges of the opening and prevents moisture flowing downwardly along the cowl from entering the vehiclebody through the ventilating opening.

Forcontrolling the passage of air through' the opening 2, -I preferably provide a cover 4 having a depending marginal flange 5 that is adapted to surround the flange on the cowl when the coveris in closed position. Fordeiiecting air downwardly through'the opening 2, l preferably provide a shield 6 that extends downwardly through the opening and that has a transversely extending flange 7 at its upper edge secured preferably by welding to the vlower face of the Vcover 4. Thefshield 6 is also provided with parallel wings 8 that extend forwardlyfrom the sideedges.thereofa-djacent to the Range 7. vSecured, `:preferably by welding `to 'the rear face ofthe shield6, 1s a hinge bracket providea handle 14 having-a fiatextenlsion` 15 that is secured'preferably by rivetingto the rear face of the shield6. The handle preferably extends downwardly and rearwardly from theshield so thatthe grip 16 will be in a convenientpositionto be manip- 'ulated For automatically retaining the cover 4 'in yvarious positions of adjustment, -I prefer.

ably provide a bar or quadrant 17 thatex- 'tends between a metal/dash board '18 land `an instrument board 19 ofthe vehicle body and thatis provided adjacent l.to the rear end thereof witha centrally disposedlongitudinally extending slot 20 through which the handle 14 extends. The bar 17 is preferably vbolted. at-one end to aftransversely extending flange 21 at thelower edge of the instrument board and is provided at `the other endwith an upstanding'flange'22 that is preferably riveted to the dashboard 18.

Sleeved upon the handle 14 is a cup-shaped member 23 that is adaptedto slide along the'upper surface of the bar 17 and that is preferably pressed thereagainstby means of a coil spring 24 that surrounds the`handle. The upper end of the spring 24 is preferably secured to a transversely extending reinforcing fiange- 25 at the lower edge ofthe shield 6, while the lower end iof'the spring 24 preferably rests within the cup-shaped member 23. A tubular member 26 surrounds the handle 14 within the coils ofthe spring 24 and is preferably formed of resilient materi al to prevent the spring from'rattling.

Slt)

The bar 17 preferably inclines gradually downwardly from the dash board 18 to a point slightly beyond the forward end of the slot 20 and is preferably'offset down-` wardly as shown at 27 adjacent to the instrument board 19. The slotted portion of the bar is preferably bent to provide a plurality of detents or corrugations 28 for receiving the cup-shaped member 23 to hold the handle 14 in various positions of adjustment. i

In use, the handle 14 may be readily moved forwardly or rearwardly to raise and lower the cover 4. When the handle is positioned at the rear end of the slot 20 ,as shown by full lines in `Figure 3 the pressure exertedy by the spring 24 against the cupshaped member 23 is in advance of the handleso that the cover 4 will be retained in closed position, whereas,.when `the handle 14 is moved to the position shown by dotted lines in Figure 3 the pressure exerted by the spring against the cup-shaped member is in rear of the handle, consequently, the cover 4 will be retained in raised position.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to whatisherein Yshown and described and that such changes may be resorted to when desired as fall `within the scope of what is claimed. y
